At a key meeting of the BJP today, Prime Minister Narendra Modi launched a blistering attack on the Congress and BJP chief Amit Shah declared that the party will rule for another 50 years. "PM Modi told party workers that we must win every constituency, every booth," Union Minister Ravi Shankar Prasad told the media after the two-day national executive meeting. Ahead of the next year's assembly elections, the strategy session focussed on censuring the opposition. The national executive comes as the government is facing opposition challenge over a number of issues, including the fuel price hike and Assam citizens' list.
